Re: [diesel_mercedes] Valve adjustment on a 300TD 1980

 

I did a valve adjustment on my 300TD earlier this year.
Either two or three of the ten were tight.
I can't remember now.
Before that was 3 years ago.
Maybe 4 were tight then.
Still . . . it made some difference.
The OM617 in my jeep was another story.
Did them 2 months ago.
At least  half were tight.
Made a real difference.

By the way . . . When I first put that engine in my jeep last year it would surge and rock at idle and would almost certainly die several times before it warmed up. Now (after 6 months, a few Italian tune-ups, and several thousand miles) it starts pretty well and the rocking and surging is gone at cold idle. It's surprising. As if using it has healed it.
Comments?

I've gone 40 thousand miles since my last valve adjustment.  The last time I checked the adjustment was still good.  Has anyone else experienced a not tight situation?  Isn't the clearance supposed to shrink after 20k?  I usually adjust on the slightly loose side.  On my other 240 D's they always tightened up where I couldn't get the feeler gauge in..  Lawrence Rhodes

[diesel_mercedes] Tranny ' Flaring '

 



There was much written about this a while ago ;

It seems to mostly do with the amount of vacuum reaching the tranny as you're driving .

The ideal (as I understand it) is to have maxumum vacuum @ idle and it should drop as you accellerate , reaching zero vacuum @ WOT .

I found that replacing all those little rubber hose bits and ' Y ' connectors helped a lot , then I replaced the plastic ' switchover valves ' on the top of the rockerbox , that really seemed to do the trick .

There's also a modulator adjustment done under the car after cleaning off a bunch of crud , doing this one is sensitive as you firm up the shift at the same time raising the RPM point of shiting....

Have you yet done a basic tranny service including draining and re filling both the tranny and the torque converter ? plus replacing the tranny's filter ? .

Gotta do all the basics before touching the tranny .

Depending on where you're located , getting a nice W126 interior shouldn't be difficult , there's basically two styles so once you match the colors you're good to go .

sounds great.  I recently purchased a 265,000 mi 85 300SD.  Starts good runs good interior is something of a mess and I have to rework the rear windows so that they operate.  They are both disconnected internally.  A winter job. That and a brake job.  My main problem is that the engine revs unduly at the shifts.  I think there is a relatively simple remedy for this but I can't remember what it is .  Can anyone help?

Some here may recall I recently had a fellow M-B'er test my spare injectors and found several ' droolers ' as well as all out of spec. on the '82 240D Slushbox , I replaced them and changed the two fuel filters , up graded the fuel tank to a lager one and began heavily dosing it with Startron as the clear plastic primary screen kept filling with both coffee colored fuel and tiny bit of jet black crud .

I refueled the car from essentially dry the other day and changed the clear intake screen and again , added a quart of Startron and motorvated away with SWMBO , didn't get a chance to peer under the hood again until Saturday evening ~

I got on the Freeway and needed to cross five lanes to the left exit as fast as the poor old 2.4 Liter engine (with one bad hole0 would go , shut off the AC , shifted into thrird gear and pinned the throttle , it took off fairly well for a four cylinder Diesel , I up shifted into fourth gear at just under 40 MPH and felt it surge ahead , there was traffic behind me and closing so I kept the throttle pinned

and was pleased to see the speedo climb past 85 MPH and pin against the peg ~ the engine was roaring right along and was still accelerating , as soon as i wasn't holding up traffic I eased off it and back to 60 MPH , it only raised the coolant temp to 90° C , a very good thing indeed .


When I arrived in Los Angeles I popped the hood for a look see and was pleased to see the clear filter was clear of any debris or cloudy fuel .


Maybe , just maybe I have turned the corner here and have killed off the fungus .


I hope so as I'm keen to get the cylinder head and oil pan off this engine and do a periodic overhaul and comprehensive gasket/seal replacement and rebuild the tranny too .


Fingers crossed ! .


It's _never_ been able to go over 80 MPH indicated before in the whole time we've owned it , I surely wish I'da had my Garmin so I could have tested the actual top speed .

[diesel_mercedes] OM616 (four cylinder) Throttle Rod

 



There's no picture here.......

The like to E-Bay only had 115 parts , 123 are different and apparently vary over the various years .

Still looking and accepting help ! .

TIA ,

Here is an eBay search:

Which one is this picture?

I need the black plastic cover that hides the vacuum switches on top of the rocker box .

It is slightly different from the OM617's I have spares of .

Also , one of the throttle rods is maybe  damaged , it appears to be designed to extend a bit but it's been jammed .

" Idle Path Rod " .

I'd love some decent diagrams for the 1982 240D's switchover valves , not in my factory service manual .

As always , I will travel to get these parts , pay for them and take them off your greasy old junk engine or dig through your parts boxes....

TIA ,

[diesel_mercedes] Fuel Economy Check '82 204D Sluchbox

 

 563 miles , (LOVING this new bigger fuel tank !)  , 29.6 MPG .

Statron used .

I was going to run it dry but SWMBO needed to go to the eyelash parlour this morning so I filled it up on the way , changed the clear plastic intake screen , it has slightly cloudy fuel and a few chunks floating 'round in it .

[diesel_mercedes] Eckler's M-B Parts

 

O.K. ;

I got my new window lift from them already , that was very fast .

I think I'll go ahead and install it in the door now , not wait for the re paint job as I like to open the window a lot and can't right now .

It feels very light but looks to be made well .

Time will tell .
